DRILLING METAL
There are two rules for drilling hard materials.
First, the harder the material, the greater the
pressure you need to apply to the tool. Second,
the harder the material, the slower the speed.
Here are a couple of tips for drilling in metal.
Lubricate the tip of the bit occasionally with
cutting oil except when drilling soft metals such
as aluminum, copper or cast iron. If the hole to
be drilled is fairly large, drill a smaller hole first,
then enlarge to the required size, it's often
faster in the long run. Maintain enough
pressure to assure that the bit does not just
spin in the hole. This will dull the bit and greatly
shorten its life.
1. The charger was designed to fast charge
the battery only when the battery
temperature is between 32˚F (0˚C) and
113˚F (45˚C). If the battery pack is too hot or
too cold, the charger will not fast charge the
battery. (This may happen if the battery pack
is hot from heavy use). When the battery
temperature returns to between 32˚F (0˚C)
and 113˚F (45˚C), the charger will
automatically begin charging.
2. A substantial drop in operating time per
charge may mean that the battery pack is
nearing the end of its life and should be
replaced.
3. Remember to unplug charger during
storage period.
4. If battery does not charge properly:
When the battery is empty, the tool is
switched off by means of a protective circuit:
The tool no longer operates.
To prevent damage to

battery, do not continue to
press the On/Off switch after the tool has
been automatically switched off.
The battery is supplied partially charged.
Completely charge the battery before using

Before using an accessory,
W RNING
be certain that its maximum
safe operating speed is not exceeded by the
nameplate speed of the tool. Do not exceed
the recommended wheel diameter.
RUNNING NUTS AND BOLTS
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attachments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
a. Check for voltage at outlet by plugging
in some other electrical device.
b. Check to see if outlet is connected to a
light switch which turns power "off"
when lights are turned off.
c. Check battery pack terminals for dirt.
Clean with cotton swab and alcohol if
necessary.
d. If you still do not get proper charging,
take or send tool, battery pack and
charger to your local Skil Service
Center. See "Tools, Electric" in the
